What is the primary function of a safety valve in a boiler?

The primary function of a safety valve in a boiler is to relieve excess pressure. This component is crucial for ensuring the safe operation of the boiler. When the pressure within the boiler exceeds a predetermined limit, the safety valve automatically opens to release steam or water, thereby preventing potential explosions or damage to the boiler system. This mechanism protects both the equipment and personnel from hazardous situations that could arise due to overpressure.

Regulating temperature, controlling water flow, and heating water are all essential functions within a boiler system, but they are typically managed by other components, such as temperature controllers, feedwater valves, and burners. While these functions contribute to the overall operation of the boiler, the safety valve's unique role in pressure relief is vital for maintaining safety and integrity in boiler systems.
